TCustomTreeView.SelectionIsHidden function
Indicates whether the highlighting for a selection node is actually hidden (not visually displayed) or displayed in a "grayed" or "dim" state when the control loses focus.
Declaration
function SelectionIsHidden: BooleanFunction result
Returns True if selection node(s) are available but not highlighted, "grayed" or "dimmed".
Description
When HideSelection is True and the control is not focused, the selection highlighting is really hidden only in Delphi mode. Lazarus mode ignores the HideSelection setting.
Use HideSelectionMode to control the behavior used for selection nodes when the tree view control loses focus.
Added in LCLversion 5.0.
